Bamboo Charcoal for filtration

As you all probably know bamboo charcoal is the best when it comes to charcoal filtration for water.
It just so happens I have a stand of bamboo on property and we burn all the time.

What I'm after is an acrylic tank of some type that I can open up and load the bamboo charcoal into it. It would have to have a 1/2 inlet and outlet as the well water will pass through it. Anyone know of any such tank?
Thanks
